At times, you may need to disable automatic recoveries during replication and auditing for certain data groups because a feature in use or an application being replicated may interact with auditing in an undesirable way.
Features - Do not use automatic recoveries during auditing and replication in any data group that is using functions provided by the MIMIX CDP™ feature. This feature, which requires an additional license key, permits you to perform operations associated with maintaining continuous data protection. By configuring a recovery window for a data group, you introduce an automatic delay into when the apply processes complete replication. By setting a recovery point for a data group, you identify a point that, when reached, will cause the apply processes to be suspended.
In both cases, source system changes have been transferred to the target system but have not been applied. In such an environment, comparisons will report differences and automatic recoveries will attempt recovery for items that have not completed replication. To prevent this from occurring, disable comparisons and automatic recoveries for any data group which uses the MIMIX CDP feature. For details, see Disabling audits and recovery when using the MIMIX CDP feature.
Applications - At times, data groups for some applications will encounter problems if the application cannot acquire locks on objects that are defined to MIMIX. These data groups may need to be excluded from auditing. MIMIX acquires locks occasionally to save and restore objects within the replication environment. Some applications may fail when they cannot acquire a lock on an object. Refer to Support for FAQs that list specific applications whose data groups should be excluded from auditing. For those excluded data groups, you can still run compares to determine if objects are not synchronized between source and target systems. Care must be taken to recover from these unsynchronized conditions. The applications may need to be ended prior to manually synchronizing the objects.
To exclude a data group from audits, use the instructions in Preventing audits from running.
